` The Ipresent invntonrelaies ioj iinprov'egf mentsyin slide Scrapers, particularly adapted for use in .buildingroads Surface' lt'anksa'nd otherV excavating or building'worlt wherein such a device is needed.' The' primaryV object oi' theinventin is the provisin f (avvii veicient scraper-'Orf l@iii-erwan'ngdeifice'iviiien' may be loaded quickly and durr'pedwithv equal facility, andv which mayV be manipulated in the operations of dumping, loading,"

and lifting. in` afsim-pl'einanner, 'thusen- .abling the operator to devote his attention to the work and yto lthe draft horse. V,The in'venf aber @ansias essentially' in terrain miei combinations and arrangements of parts as hereinafter more fullyV specified and as disclosed in the drawings. y v

In the yaccompanying drawings I. have illustrated 4one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical applicatio of the principles of my invention.

Figure 1 is a top p'lan'view of a scraper embodying my invention.

Fig. 2 is a side elevation of the scraper. Fig. 3 is a front view of the device.

Fig. 4 is a vertical sectional view of theV longitudinal bars 3 and 4. forming with the lower bars, the frame of the device. At the front the upper and lower Jframe Vbars are provide a rigid and' durable' traine, and al l .specificationsffLeaersPaieni. Patented Uov.113,.1917f.

The scoop or'slhovel 13 frame, i or rather4 .is'uspended"in" the frame; from the archba'r 14e, eitendiiig transversely of the'frafne and -h'avingf its ends '15'an'd1f6' secured .against the inner surfaces' of opposite sidewalls of the "scoorporshovel-.f

'l It will be seen also that the trunnions in their slotted postsl receive the vpressure of of the hand lever 23 the shovel may be lifted to its maximum altitudeV and held there, i l

when out of operative position, las when the scraper is being transported. In addition to also be lifted by the foot or vpedal bar 25 the manual lifting device, the. shovel may which is U-shape having its sidey arms lpivoted at 26 26 to the loose linksr25 (one atI each side of the frame) and theselinks are each pivo-ted, as at26a toa fixed, down- Wardly projecting bracket arm 27. The ends of the U-shaped pedal bar are formed with -eyes'28,' 28 through which the respective trunnions 15 and 16 pass, and it will readily be seen that by bearing down onthe bar 25 the shovel may be liftedfrom the ground, the fulcrum points beinglocated at 26 26.

Thus, after the shovel is loaded, the operator l mayv reach down with his foot, press down on'the bar and lift the loaded shovel from thel gro-und so that the devicermay betransl ported to the dump. v The dumping `or 1111-. v. f

and in Fig. l it Twill be seen that the ends of the bar are attached to the shovel at 33, 33.7 thus holding the shovel bar rigid with the shovel at all times. t will thus readily be seen that by lifting the Vlever 28 (Fig. 2l,"

and turning it to the front, the shovel will be lifted at the rear and turned forward, thus dumping the ycontents therefrom, quickly and completely and the shovel is then Vturned down by lowering the leverQS. It is evident that the two operations may be accomplished with facility and despatch through the instrumentality of the manual or pedal, levers for lifting the loaded shovel, and through the `lever 28 for dumping the load from the shovel. The apparatus is of course utilized in characteristic manner for doing its Work, and it is believed that from the above description and an inspection of the accompanying drawings it will be evident I have provided a comparatively perand rocker arms loosely connecting said arch bar and rock bar, of a shovel bar fixed at the rear upper end oit' the shovel, a lever pive otally supported on the arch bar7 and a pivoted link connectingsaid lever and shovel bar as described.

2. rthe combination with a slidable trarne comprising opposite sidek members and transverse connecting bars and slotted posts, of an arch'bar With end trunnions Vin the. slotted posts, an oscillatable shovel having a front's'uspension on said trunnions, a rock bar and rocl arms connected to said arch bar and an operating lever for said rock bar wherebyl theshovel may be elevated, a shovel bar fixedVv at the rear upper end of the shovel, a lever pivotally supported on the.

arch bar, and a pivotedlinl connecting said lever and shovel bar whereby the shovel may be dumped.

In testimony whereof I aliix my signature.
